Preheat oven to 180ºC/350ºF; line two large baking sheets with baking paper.

Whisk first flour, cocoa powder, baking soda and salt together in medium bowl. Using electric mixer, beat butter in large bowl until fluffy. Add sugar and vanilla; beat until blended. Add flour mixture and beat until moist clumps form. Mix in oats with spatula until evenly distributed (dough will be very firm). Add chocolate chips and white chocolate chips and knead gently to blend.

I love dark chocolate. When making cookies like this, I always eat them when they are still warm as the chocolate chunks are still wet and melted. YUM!!! with a glass of milk before going to bed? Well, not for me, otherwise I'll be up all night hehehe... I guess, for some people this can be the ritual anyway. I am sure everyone will love this cookies!

great looking cookies! and definitely a great way for adding fibre..which is what we usually do with leftover muesli - chuck it into cookie batter. still tastes great and i always love the bite it adds to em cookies :)
